3 Way Fridges On Ebay Opinions?

It should not make any difference to the pressure going to the cooker burners when the fridge is working on gas, if the gas pressure reduces at the cooker when the fridge is supplied with gas and running you have a problem either with the fridge, regulator or collapsed rubber feed pipe.
The amount of pressure in the gas bottle is more than enough to run both items at full chat. It's possible that the regulator has malfunctioned and only allowing say 20% pressure through, the regulator should be rated at 30mbar, I personally have had at least three regulators go west over the years, two had failed completely and one hardly let any gas through at all, so that is a possibility.
The other possibility is that the tap on the bottle has got a problem but on thing for sure is that I have a full oven and hob, a Truma 4 heater and a three way fridge all running off the one regulator plus a barbecue fitting and I can have all four running at full bore without a problem. We'll to be fair I've never had the Bb fitting running with the other three but I'm certain it would be ok.
Frankly the amount of gas that a fridge demands is minimal it's little more than a hand held cigarette lighter flame unless it's one of those doubles fridge units and then they can just be heard to roar a little 😆. I suppose you have tried a new bottle? Phil
 
The pipes reg' & fridge are all new, the reg' is adjustable I can turn up the pressure & have the cooker burners at full flame & then the fridge wont keep a correct flame, it blows its sell out

Hmmm, got to say I've never come across an adjustable regulator, how do you know what pressure your setting? The fact that the fridge flame goes out would suggest to me that regardless of what you are calling full flame on the hob it would seem that the pressure is too much, does the flame around the hob roses stand away from the roses or does the flame seem to eminate from the rose. I'd say adjust the regulator to the point where the fridge flame works well then turn on the hob and find the sweet spot where the fridge flame stays alight and the hob flame is exceptable. What make is this regulator I'd like to have a look at one, I really can't see why you would require an adjustable regulator so I'd love to have a look at it's specs and sales blurb, where did you buy it? Phil

P.s. If the fridge is new it would be very bad luck that there was a problem with the 12v side of the heater, did you get full instalation instructions with it and what is the model number.
 
I can adjust the reg' to get the hob flame as required, when the flame is "normal high" its too much for the fridge. Both fridge & reg' are cheap unbranded ebay stuff. I have the instructions but not much use.

I put the exact same fridge into my Daughters van that I built for her, I think I put some of the build pics up on here, though I really can't remember, I'll have to check but it's been a good fridge for over a year now. I had to make an extended exhaust for it out of diesel heater exhaust as the fridge was smaller than the standard Dometic ones the dometic vents which I used had to go below and above the van side strengtheners and the extended exhaust. I got hers from Amazon think it was about £450.
What was this regulator?
 
That looks good, Ive knocked up a vertical exhaust pipe to vent the fumes out the roof, Ive checked for flame problems having such a high head of ex' pipe, its makes no difference to the function of the flame. My van is a Transit MK6 2.4tdi, I binned the fuel pump & fitted a one wire pump off a 300TDI, runs like a champ & will run off anything, old veg oil, hydraulic oil etc at the mo' I have a 1000L of veg oil that was used for a release agent in the food industry it came in @ 15p a liter & its legal to use..........
 
The only adjustable gas regulators that come to my mind are the ones for running petrol generators on lpg. If it's one of those then it isn't sufficient I don't think. As Phil says you want a standard 30 Mbar regulator. Your fridge is rated at 28Mbar and your cooker should be in the same range of 20-34 Mbar.

If memory serves I think there were some higher pressure items years ago (may have been German) but not sure you would get regulators for them now. All the kit you buy these days should run on 30Mbar regular\or

Sounds good to be able to use multi fuels especially as the Orange orangutan has made a right mess of things. Sorry for late reply but we moved to a site were there has been no signal 🫠. Phil
 
Farang, I've searched ebay and can't find an adjustable gas regulator apart fron an acetylene gauge. Are you using Butane or Propane and what size bottle which supplier BOC/ Calor / or a local supplier.
If your using Butane there are several different fittings by supplier so butane is a bit of a nightmare and on the continent the fittings are even more diverse.
I really feel that you should buy a standard regulator off Ebay and try that.
You can get a "Y" piece to join the cooker and fridge if your using flexible gas pipe ( Not recommended by the way but exceptable if you do it probably and clamp the pipe so it's not vibrating all over the place ).
Other than that I personally have no other explanation as to why you have a pressure difference between the cooker/Hob and fridge. Phil.

This as available at my local farm supplies its only £7.30, Ill fit that, thanks for the help! ( its 37mbar)
 
Sorry Farang, it's 37 mb 7 mb too much you really do need a 30 mb regulator. The reason your fridge blows out is because your forcing too much pressure through, you will get away with the hob but not the fridge. Phil

Having your input I now realize that when the reg' is set correctly for the fridge flame the cooker burner flame is at whats its meant to be, I had the reg' adjusted for a more intense flame. My error, I'll just set the reg' for the fridge & accept a lower flame on the cooker...thanks for all the help!

That's a pretty standard bottle regulator for propane Phil

Edit: To expand a little, ALL bottle regs are sold for outside use only. Ideally you would use a bulkhead 30Mbar regulator

Yes I agree but Farang seemed desperate to save money and while it's not the done thing for a common bottle regulator to be used inside it's been done safely for years, ( Continentals and Arabic countries cook inside with the bottle usually under the hob ) my thinking was to achieve a 30mb state of pressure, a purchase of the standard caravan/motorhome wall mounted Gok one would be the only obvious choice. However looks like Farang has settled on turning his adjustable down 😄. Phil
 
Yes I know many who use bottle regulators inside, I only recently noticed they say outdoor use only. I carry one as an emergency spare in case my bulkhead reg packs up and I can't get one quickly. I would backed through my bbq point probably if I had to.

Any change of a pic of this adjustable regulator Farang, still not sure what it is?

Blimey Farang, if this is the adjustable regulator you bought, it's is totally unsuitable for your needs and would be dangerous to use it. How they can justify using it on a barbecue is beyond me, unless they are roasting an ox.😄
I'm not saying it is the one you chose just if it is don't use it. It's the only one I could find on ebay. Phil
 

Or even this one 0-2bar even if you adjust to 30mb it would be really temperamental and hard to get it right without a pressure gauge. Phil

P.s. However I noticed in the description it states 500mb to 2bar so they obviously admit that from 0-500mb is not practicable.
